If you are chosen by the bizarre black sphere known as the Gantz, you are already dead—yet you might be able to reclaim your mortality. First, the Gantz demands that you undertake brutal missions of madness, killing aliens hidden among the population. It is your only chance and you have no choice. You must play this disturbing game. And if you die again—and you likely will—it’s permanent.
Change is in the air for the players of the deadly game. Fed up with his aunt, Kato finds a new place to live with his little brother. Meanwhile, Kei’s attitude pushes Kishimoto away, and Tetsu’s life spirals brutally out of control.
The Gantz calls the players for another round. Among the new faces gathered before the sphere: a television evangelist that thinks he has all the answers and a girl who seems willing to give Kei the attention he seeks.
When Kato shares what he knows in an effort to help the new players, the evangelist begins to think something sinister is afoot. The holy man learns just how correct he is as the game’s new targets make their presence known.
The team’s efforts to defeat the giant aliens are hindered by two thugs who are brutally tormenting a homeless man - the very same homeless man that Kei and Kato encountered just before their deaths.
Kei goes on a rampage, leading the battle against the giant aliens. Yet another unhappy surprise awaits the team.
After claiming victory against the giant red and green aliens, the group boldly rushes into battle against the smaller statues. Soon enough, they find their numbers thinned by an enormous new enemy.
Several players meet with gruesome ends as the living statues continue their onslaught. Tragically, one of the mutilated victims is someone very dear to Kato and Kei.
The carnage continues and truly no one is safe. As wounded Kei struggles to stay alive, his teammates fall one after the other. When the final foe is defeated, only one player will be around to see the score.
Kei returns to the Gantz and finds many familiar faces will be joining him in battle. Unfortunately, Kei is shocked to see that their alien prey wears a familiar face as well.
With no explanation, the Gantz has chosen Kei to be hunted. At first, the rest of the players are unsure of what they should do - but the black sphere soon helps them decide that Kei should die.
The new players are beginning to see just how dangerous the two bum-killing freaks really are. As the situation escalates, the members of the team look to the one person who might be able to help them survive - Kei.
Madness is taking over as the team hunts the two brutal maniacs in their midst. The number of fatalities grows quickly, and Kei begins to understand that the Gantz might not be his worst problem.
Facing his deadliest foe, Kei is forced to question everything he’s learned—and all that he has lost—in the twisted world of the Gantz. No matter if he lives or dies, for Kei, the game now ends.
